Abstract:

 



In this study the effect of ultrasound of the cerium
exchange was studied. The results were compared
to those obtained from traditional batch exchange method. Contact time,
initial cation concentration (fold equivalent excess) and the types of the
ultrasound were studied. Ultrasonic
probe, which is the most effective method, enhanced the
replacement of Na+ ion with Ce3+ ion in the extra-framework of zeolite up to 73 % by applying 5 consecutive
ion exchanges. The cerium in the solution caused to be formed cerium oxides on the
crystal surface occluding the pores. Thus the
specific surface area of cerium exchanged zeolite was decreased due to formation
of cerium complexes on the surface and into the pores.
